CHIMNEY AND'VENTlLATlNG-SHAF'T TOP AND THE LIKE.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed July 27,1905. Serial No. 271,527.

To all whom it may concern:

Be it known that I, AUGUST IIOLTZHEUER, engineer, a subject of the King of Prussia, residing at No. 30 Rotendit'molderstrasse, Cassel, German Empire, have invented new and useful Improvements in Chimney and Ven tilating-Shaft Tops and the Like, of which the following is a specification.

My invention relates to a tubular extension or pot for application to chimney and ventilating shafts and the like.

The new pot consists of a pipe or tubular member which owing to its flexibility can be blown by the wind more or less out of its normal position, while on account of its resilience it resumes its initial, extended position on the wind abating.

In manufacturing the improved device, flexible, resilient, socalled metallic hose is particularly suitable as material.

My invention is illustrated partly in section in the accompanying drawing, in which A is the chimney shaft and a the flexible pipe applied to the same. In the figure the dotted lines indicate the bent positions into which the pipe may be blown by the wind.

Having thus described my invention, what I claim is In combination with a chimney, a straight flexible and resilient metallic pipe having its lower end held in said chimney and its upper end free.

In witness whereof I have hereunto signed my name this 13th day of July 1905, in the presence of two subscribing witnesses.

AUGUST HOLTZHEUER.
